Small pets pack a lot of personality into a little package — but each species has its own needs. Whether you’re considering a rabbit, guinea pig, hamster or gerbil, this Small Pets 101 starter guide covers the essentials of habitat, diet, enrichment and care, with supplies available on ASM Pet Market.

Choosing the right small pet

Start by matching the animal to your life. Consider space, how social the species is, how much handling it enjoys, its lifespan, and whether it’s active during the day or night. A guinea pig that loves company is a very different commitment from a solitary hamster. Research first; a well-matched pet is a happy pet — and a happy owner.

Habitat and housing

The enclosure is your small pet’s whole world, so prioritise space, security and ventilation. Provide species-appropriate bedding, several hiding spots, a clear food and water area, and easy-clean access. As a rule, bigger is better — generous room to move, forage and explore prevents boredom and stress. Browse habitats and accessories in the full catalogue.

Whatever the minimum enclosure size you read, treat it as a floor, not a target. Extra space is one of the easiest upgrades to your small pet’s quality of life.

Diet and water

Diet is species-specific and worth getting right. Many small herbivores depend on unlimited quality hay plus a measured species-specific pellet and fresh greens; others need a balanced seed-and-pellet mix. Always provide clean fresh water and avoid sudden diet changes. When in doubt, research your exact animal and ask an exotics-savvy vet.

Enrichment and activity

Small pets are curious and need stimulation to stay healthy and content. Offer safe chews (important for continuously growing teeth in many species), tunnels, foraging opportunities and, where appropriate, exercise wheels or playpens. Rotating enrichment keeps their environment interesting and prevents boredom-related problems.

Handling and health

Build trust slowly with gentle, frequent, low-stress handling so your pet learns you’re safe. Watch for healthy signs — bright eyes, steady eating and drinking, normal droppings and activity — and find an exotics-experienced vet before you need one. Many small pets hide illness well, so changes in appetite or behaviour deserve prompt attention.

Species quick notes

  • Rabbits — need lots of space, hay-based diets and companionship; intelligent and trainable.
  • Guinea pigs — highly social, often happiest in pairs, vocal and gentle.
  • Hamsters — Syrians live alone; nocturnal; love wheels and burrowing.
  • Gerbils — active, social diggers that enjoy deep bedding to tunnel in.
